other object is to provide a tiltable equalizer 'block for preventing the cramping of axle bearings due to an unbalanced load on the axle box. To these ends-and to improve generally and in detail on devices of this character, the invention also consists in the various matters hereinafter described and claimed.

, The invention, in its broader aspects, is not necessarily limited to the specific embodiments selected for illustration in the accompanying drawings in which Fig. 1' is a longitudinal-vertical section of a car journal box and associated parts. Fig.2 is a central transverse section. F i'g. 3 is a plan view.

Fig. is a perspective view of an equalizer 2 block.

Fig. 5 is a longitudinal central section of the equalizer block. I

Fig. 6 is a plan view of a modified form of equalizer block and Fig. 7 is a section on the line 7.-7 of Fig. 6.

The numeral 10 indicates a shaft or axle with stepped cylindrical surfaces 12 and 14,

a sleeve 16 being shrunk or pressedon the surface Hand held by a split ring 18. Two sets of roller bearings 20 are interposed between the sleeve 16 and a lining 22 in the bore of a journal box or casing 24. The outer end of the box has an out-turned flange 26 to which an end cap 28 is fastened by bolts 30, the .bolts being welded to the flange as. indicated at 32. The end cap has a lug 34 extended inwardly into a slot 36 in a retainment ring 38 to hold the latter from rotation. .The retainment ring is provided with a square opening 40 receiving a square thrust block 42 and spacing plates 44, the block and spacing plates ,being held tightly against the end cap' by a bolt 46 and nut 48. The bolt has square collars 50 cast in a square opening of the thrust brace the flat sides 84 of the projection. The

block to hold the bolt from rotation. The

thrust block is preferably of brass and its inner end face'opposes the end face of the axl e,-lubr'ican t being lifted'to the' opposing 1faces by a'wic'k 52. The wick extends from a :lubricant reservoir 54 in the box,- through a 55 boss 56 of the retainment ring 38, to a recess in the thrust block. Lubricant is admittedthrough a hollow boss 58 in the end cap, and, after lubricating the thrust face of the axle,-

collects on a rib 60 and is thrown off into an 60 annular groove 62 of the retainment ring and drains through a notch 64 to the bearings. The retammentring has grease grooves. at 66 fitting the bore of the box and partitions oif I i the end of the axle from-the reservoir so that 05 the oil must pass through the bearings before. returning to the reservoir through-a vertical passage 68 and inclined drain passage or core I 7 0 at the bottom of the box. The inneror rear end of the box has grease grooves closely 70 fitting the surface 12 of the axle and lubricant, working inwardly of the axle, is arrested by a washer 7 2, rib 7 4 and groove 76. r f

The top of the axle box is provided with an upwardly extending projection 80; which is arched longitudinally of the axle to provide a cylindrical seat 82. The sides of the projection are :fiat as indicated :at 84 in Fig. 2.

Mounted on the projection is a tiltable equalizer blockyor plate 86 having, on its underside. a cylindrical seat 88 fitting the seat 82. The equalizerblock can thus tilt longitudinally of the axle and axle box but is prevented from tilting crosswise or coming off by depending side flanges 90 which em-'.

block slants upwardly and outwardly at the ends as indicated at 92- to provide clearance with the box and. on the upper side, the ends are provided with spaced ribs 94 and 96- forming cross grooves or seats 98 ,for frame members such as the usual equalizer barslQO which carry the weight of the car body. The seats 98 are equally spaced from the axis of tilting and the load carried bythe bars 100 is [always transferred or applied by the equalizer block 86 to the center of the box. This preventscramping of thebearings due to an unbalanced load.. In the modification of Figs. 6 and 7, each seat comprises oppositely inclined faces 102 meeting at a rounded pro tuberancc 104: to fit a slot in the equalizer bar,

' thereby allowing the bar to rock.

' \vi'th outwardly exten Both sides ofthe axle box are provided ding spaced projections 106 which straddle the usual car frame pedestals (not shown). Each sideofthe boxwelded to ribs 114 on the box. The side arms 116 of the Wear plate are co-extensive with the spaced projections 106 of the box.

Iclaim:

1 In a device of the character described, in combination, ajournal box, a-shaft journa-lled in the box, an equalizerblook seated on the box to tilt freely longitudinall of the shaft, means for preventing the bloc from moving crosswise'of the shaft, and equalizer bars-seated on. the top of the tiltable block; substantially'jas describedi 2. In a device of the character described, in combination, a. journal box having an up ward projection provided with acylindrical seatarching longitudinally of the box, and an equalizer block havingacylindrical recess fitting the cylindrical seat, theblock having side flanges embracing the sides of the proj ection; substantially as described. Q
